In the accompanying drawings :Figure l is a vertical sectional view of a can opener constructed in accordance with my invention. Fig. 2 is an inverted plan of the same. Figs. 3- l are detail Views.

In the embodiment of my invention I provide a circular housing 1 which is formed with an annular base flange 2, is made of sheet metal, and is provided at opposite sides with oflsets 3. A shaft 4 eX tends across the lower portion of the housing, is mounted in bearings 5 in the wall of the housing, is provided with a spur gear 6 and also has a crank handle 7 at one end to enable said shaft to be readily threaded.

A circular plate 8 is fitted in the base of the housing, to close the lower end thereof, is provided with an opening 9 through which one side of the gear 6 extends, and is also provided with spurs 10 which are formed integrally therewith and arranged at opposite sides thereof and are provided with shoulders 11 which fit in the oflsets 3 of the base flange of the housing. The plate 8 is secured to the base flange of the housing by bolts or other suitable fastening devices 12. I also provide a circular cutter plate 13 which is arranged on the outer side of the plate 8 and is mounted for rotation on a centrally arranged spur 14 which is secured to the plate 8, The cutter plate has gear openings 15 for the reception of the spurs of the gear 6 so that the cutter plate may be revolved by said spur gear, as will be understood. At one side of the revoluble cutter plate is a knife 16 which is integral therewith and arranged at right angles thereto Specification of Letters Patent.
